IMPROVEMENT INMACHINES FOR MAKIANG WIRE HEDDLEEYES.

Specification forming partof Letters" Patent No. I,'285, dated July 1l, 1854.

Be it known that l, THOMAS CLEGG, of Andover, in the county of Essex and State of Massachusetts, have invented a new and use- Eycs of Wire; and I do hereby declare that the same is fully described and represented in the following specification and the accompa nyin g drawings, letters, figures, andreferences' thereof. A

Of the said drawings, Figure l represents a side view of a wire heddleeye as made by the said machine. Fig. 2 is a top view of the machine. Fig. 8 is an elevation ot' that side of the machine on which the driving-pulley is placed. Fig. 4 is anelevation of the oppoi' is a transverse and vertical section taken through the main drivingand twisting shafts. Fig. is a-vertical and longitudinal section and showing the compressor-jaws.

Such other figures as may be necessary to afull and complete description ofthe machine will be hereinafter mentioned and described.

In the said drawings, A represen ts the main the machinegl the main driving-shaft, which is placed in the position as represented in the band, made to work around a drivingpulley, C.

At the front end of the machine is a set of feed-rollers, l) E, which are placed, respectively, upon horizontal and parallel shafts F G,wliich shafts are made to rotate in suitable bearin gs, and to connect by two gears, H l, (of equal dian1eters,) placed, respectively, upon the said two shafts. rlhere is a smaller gear, K, fixed on the outer end of the shaft G, such gear being made to engage or connect with a train of gears, L M' N, arranged as seen in the drawings. This train receives an intermittent rotary motion by a sectoral gear, O, during the revolution of such sectoral gear, which is placed upon the side of a larger gear, P. rlhe said4 gea-rl) is fixed 011 one end of a horizontal shaft, Q, and receives its rotary motion by means of a pinion-gear, It, fixed on the driving-shaft B. The directions of the rotation of the several gear-wheels are denoted by'arrows marked upon them. The upper feed. roller is pressed down toward and upon the other, or the wire made fast between them, means of a spring, S, which is applied to a stirrup, T, that embraces the shaft ofthe upper feed-roller near one' end of it,- the bearing of suchend of the shaft being so made as to allow of a little vertical play to the shaft.

In the drawings, U represents the wire from which the eyes are to be formed. It is passed in between the two feed-rollers, and by them fed forward toward the bending and twisting machinery as fast as occasion may require. From the feed-rollers the wire passes through a round hole made in a stationary steel plate, V, which has on its rear side a knife, W, the

oftieeof which is to cut oi the wire or separate from it a piece of sufficient length to forni a heddle-eye; A rear side view of this knife and the plate V is given in Fig. 9. The said knife, formed 'like one of the blades of a pair of shears, turns on a fulcrum or pin, X, and is moved away from the wire during the time that a sufficient length of it to form a heddleeye is passing through the steel plate V byV means of a cam, Y, fixed upon the side of a l gearvwheel, Z, fixed upon the shaft Q. As soon as this cam ceases to act upon the lo wer end of the lever of the knife W, a spring, a', applied to the lever and the fraaie, is set free, so as to react and move the knife against the wire and cause said knife to separa-te from the wire a blank or piece of sufficient length .for the formation of the heddle-eye. On passing onward from the plate V the wire is ina-de to extend into and work through two guide-pliers, b c, whose purpose is to receive the end of the wire and guide it properly toward -the pin, around which it is afterward bent. Each of these guide-pliers is provided with a short semi-cylindrical groove, d, which has a daring mouth,c, as seen in Fig. 10, (which is a top View of thelower and stationary part, b, of theguide pliers,) the under side ofthe upper guide wireplier c being formed with a similar groove. The said guideplier c is a bent lever turning on a fulcrum-pin,f, and operated in one way by a cam, g, (fixed on the shaft F,) and in the other by a spring, h, which presses the tail ond of the lever against the shaft and cam.

An un der side view anded ge and side .views of this die are given in Fig. i3, wherein I ,it-is shown as formed of three projections, u c Jai- One of these projections-viz, themiddle` one, v., carried between the two bent legs of the wire y hlank,1while each of the other. projectious, u,v

a2, that is jointed to the carriage u. The said cam is xed on a shaft, t2, that receives its rotary motion by means of a gear, c2, that engages with the gear Z, hereinbefore described.

The depression of the carriage u is produced by the reacting power ofa sprin g, d2, arranged as seen in the drawings. As soon as the rotary gear 'v' is elevated above the slide-gear t, such slide-gear is,by a spring, e2, thrown forward into gear with the rotary gear t. Next, the sectoral gear 0 comes into operation with the gear s and produces a simultaneous rotation of the shafts q k and the rotary lgear t. While this is taking place the wire blank is held rmly on the Vpins l and yf, and by means of the stationary rest t and the mova- 4 ble die s, and also by the twojaws d e. The

consequence. is Athat the wire blank will be twisted between the pinl and the movable die s also between the movable die s and t-he pin y', and also between the pin y and the stud p. At the nextoperation the slide-gear t' ismQved backward by the action of a fork-A levenjf'the upper ends of the fork of said lever being provided with inclined planes or cams g2 g2, which are thrown up, respectively, against arms h2 h2, that extend from a tubular shaft, i2, of the slide-gear t. The forked arm of the lever f2 is depressed at the proper time by a cam, k2, that is fixed on a shaft, b2, and made to act against a stud, l2, projecting from baid forked arm is also raised at the proper time'by the reacting power of a spring, m2. As soon as the slide-gear t has been moved backward, and beyond the rotary gear fv, the said rotary gear 'v' is depressed entirely below the wire blank; When the vertical slide-frame z" is depressed so as to force the jaw d' toward the jaw e', it `carries a forked piece of metal, n2, down upon and astraddlel of the stud p and the wire bla-nk, the same 'serving to hold the wire blank close against the stud. When the slide-frame z is elevated, it, as a matter of course, will lift the fork n2 entirely above the stud p. This being the case, the next operation is to move the carriage f on its rod g', so as to carry the twisted wireblank in between'the iiatteningjaws, as will be hereinafter described. Before, however, this can be accomplished, a small projection, o2, that extendsupward from the fork of the for-klever f2, has been elevated against the Wire blank, so as to throw it entirely off the pin l,

such elevation of such projection occurring at the' time of the elevation of the fork-lever, as hereinbefore described. The movement of the carriage f is effected by the action of a rockerarm, p2, which i's formed as seen in Fig. 4, and turns upon a fulcrum-pin, q2, arranged at its lower end. -A bentarm, 72, extends from the arm p2, as seen in the said hgure, and is acted upon by a cam, s2, placed in the onter'end of the shaft b2. The upper end of the arm p2 `is forked and straddles a screw-pin, t2, projecting from the carriage f', which carriage is moved in one direction on its rod g when the cam s2 acts against the bent arm r2. lhe return of the carriage or movement in the opl positc direction is produced by the reacting power of one or more springs, ui, appliedV to the main frame and the arm p2, as seen in Fig. 4.

\Ve have heretofore spoken of the pressurejaws. rlhey are shown at vzw, thelowerone namely to2- bein g stationary, while the upper one is movable, or is fixed upon a lever, m2, which `turns upon a fulcrum, y2, and has its tail end elevated by a cam, z2, fixed upon a shaft, a3, which receives its rotations from a train of gears, b3, c3, and d3, made to engage with the gear P. The object of the pressurejaws is to firmly compress the metallic eye, and particularly the twists thereof, and so flatten said twists as to make them in thickness in one direction equal to or about equal to that of the wire used.. The object of this flattening or compression of the twists is to prevent the warp-thread, when the metallic heddle or eye is used, from sticking or catch- .ing in the twists of the wire. When the carriagef' is moved upon its rod g toward the compressor-jaws', these jaws are open to receive the twisted wire blank which is carried in between them, and they are firmly closed upon it and'perform their office of compressing the twists of it. This being accomplished, a lever, c3, is moved by a cam, f3, (placed upon the shaft a3,) against the jaw d', and lifts itabove. the blank, so as to entirely release the said blank from the carriage f and allow the blank to rem-ain between the compressorjaws while the carriage is moved backward into the position for the reception ofthe next blank. During the backward motion of the carriage the blank is discharged from the i presser-jaws (they being supposed to be open) by the action ot' the stud p', or small stud g3, placed upon and made to project from the inner-side of the carriage. 1f desirable, a small knife may be applied to the side of the presserjaws, and so made to operate as to cut off the surplus portions of the eye-blank previous to its discharge from the compressor-jaws. The upper jaw of the compressor-jaws may be moved away from the lower jaw by the weight of the tail of its lever, or by additional weight, or a spring applied thereto.
